Alec was ordered by Manticore to watch and observe, Robert Berrisford then when he got his trust, assassinate him.

Alec got out of the black car he was in, wearing a black suit and tie. Then he went to the doorbell, right next to the automatic gate and pressed it.

He pushes the glasses up on his face, and put his hands together in front of him

The gate opened and he went right up to the front door and it opened, showing Robert.

Alec: “Hi, I’m here to help your daughter with piano lessons.”

Robert: “Right this way.”

Robert shows Alec upstairs to your room, and he saw you right there, playing the piano.
